Earth is an amazing planet, and the one that matters most to us. Let’s have a conversation about it.Sun, 04 Dec 2016 07:41:51 +0000hourly1https://wordpress.org/?v=4.5.4By: Benefits of Himalayan Salthttp://earthobservatory.nasa.gov/blogs/earthmatters/2013/12/16/december-puzzler-2/#comment-17310

I’m sure the linear triangle bottom right is significant, maybe signifies that this is time lapse and has something to do with predator pathways. (Total stab in the dark from a non-scientist )

Fri, 20 Dec 2013 16:25:37 +0000http://earthobservatory.nasa.gov/blogs/earthmatters/?p=4301#comment-13315I’d say the picture is located south of Lake Afrera, Ethiopia (its southern tip is seen in dark blue), and we’re looking at the heat signature of hot air streams (in purple) coming from the currently erupting Erta Ale volcano, north/north-west of the lake.

Thu, 19 Dec 2013 05:37:10 +0000http://earthobservatory.nasa.gov/blogs/earthmatters/?p=4301#comment-13301It’s the Benguela and Agulhas currents south of the coast of South Africa. Temperature or density could be the scale used, most likely temperature based on IR.

Wed, 18 Dec 2013 16:46:27 +0000http://earthobservatory.nasa.gov/blogs/earthmatters/?p=4301#comment-13296I, too, agree that it seems to be a false color image (or thematic map) of heat variation, similar to the image – http://earthobservatory.nasa.gov/IOTD/view.php?id=81562, where the darker colors represent cooler temperatures and the lighter ones warmer temperatures. If this is true, the patterns in the image must give us enough information to deduce the location of the image.

From the image, we can see that the northern blue area is the coolest, like a body of water (at first glance, the southern portion of Lake Michigan?) but then the patterns do not reflect the urban environment found there. The city of Chicago would be much warmer than the surrounding area due to the heat island effect. In this image, the darker area to the south west is cooler than the immediate coastal area, perhaps due to changes in topography or the presence of a river in the area, where the riverbank area is has more vegetation than the surrounding area, and is therefore cooler.
